Abstract

This study investigated human anterior cingulate cortex (ACC) involvement during a task that dissociated expectancy violation from social rejection. Across two studies, participants underwent functional magnetic resonance imaging while making social judgments and receiving fictitious feedback that was either positive or negative and consistent or inconsistent with their expectations. The results demonstrate that the dorsal ACC is sensitive to expectancy violations, whereas the ventral ACC is differentially responsive to social feedback.
